Title: Fine particle separating apparatus
Inventor: YAN EBE RORANDO RAGERUSUTETSUT
IPC: B04C5/103
Filed: 1984-08-24
Abstract: For the separation of particles, e.g. liquid drops, from a gas stream a vessel with an internal labyrinth is used in general through which the gas is conducted, whereby the particles are thrown out against the walls of the vessel and flow to the bottom of the vessel where they can be collected. Such known arrangements present great flow resistance and do not produce air which is sufficiently clean to be reused and applied under sterile conditions of the type prevailing in aseptic packing machines. 
<??>An arrangement for the separation of particles from a gas stream in accordance with the invention is provided with a helical guiding element (8) and a collar (9) fitted at the end of the same which is designed so as to have drop-forming elements (12). Consequently, on the one hand a strongly rotating movement is imparted to the air at a relatively low flow resistance, on the other hand it is processed by the drop-forming elements of the collar, which results in high capacity as well as effective separation.

Title: Differential amplifier circuit
Inventor: NAGANO BUNICHI
IPC: H03G3/10
Filed: 1984-08-22
Abstract: PURPOSE:To vary digitally the gain of a differential amplifier circuit by connecting emitter circuits of transistors (TR) constituting the differential amplifier circuit in parallel and switching them through analog switches. CONSTITUTION:Emitters of TRs 1 and 2 are connected to a constant current circuit CI through parallel-connected resistances R11 and R21, and R12 and R22, and connections of those resistances are switched through analog switch FETs 11 and 12, and 21 and 22. Further, those switch FETs 11 and 12, and 21 and 22 are connected to the same signal system and operated at the same time. When signals V11 and V12 are inputted to the differential amplifier circuit, the potential difference between those signals is amplified with a gain G. The gain G is varied by operating said switches and varying the composite resistance value between the emitters of the TRs 1 and 2 and circuit CI. Consequently, the digital signal of a microprocessor, etc., is inputted directly and the gain is varied digitally.

Abstract: PURPOSE:To obtain a good contrast without being obstructed by an external light, by providing a light absorbing means on a partial area of the first face and the second face of a prism element. CONSTITUTION:On an incident side face of a light transmissive plate 12, a prism element 13 whose section is a triangular shape is arranged. The prism element 13 is constituted of the first face 14 being a refracting surface and the second face 15 being a total reflecting surface, and also, in an area of the faces 14, 15, a light absorbing means 16 is provided. An external light beam which is made incident at a roughly vertical angle transmits refractively through the second face 15 and passes through to the back of a screen. Among external light beams which have made incident at a large angle, a light beam passing through the vicinity of a crest part of the element 13 also transmits refractively through plural prism elements several times and passes through to the back of the screen. A light beam passing through the vicinity of a trough part of the element 13, namely, the area where the light absorbing means 16 has been provided transmits refractively through plural prism elements several times, and thereafter, an incident angle to the second face exceeds a critical angle and said light beam is brought to a total reflection and about to be emitted to the front of the screen, but absorbed by the light absorbing means 16. In this way, a good contrast is obtained without being obstructed by the external light.

Title: Direct-current brushless motor drive control circuit
Inventor: YONETANI KATSUYA
IPC: H02P6/06
Filed: 1990-07-02
Abstract: PURPOSE:To prevent faulty start by vibrating an output shaft in low-speed operation such as start of a motor and stopping rotating the motor when the rotation direction of a rotation direction indication signal does not agree with that of a Hall rotation direction discrimination signal detected by a element. CONSTITUTION:When a rotation direction discrimination signal and a rotation direction indication signal which are detected from a motor 12 agree, a signal is transmitted from a monostable multi-vibrator 24 to a speed amplifier 32 via an LPF 28 and the motor 12 continues to rotate. If the signals disagree, a speed signal is not entered to the speed amplifier 32 because a rotation continuation signal entered to the LPF 28 is at level L. Therefore, the motor 12 is stopped. When a load put on an output shaft in low-speed operation in starting the motor 12 vibrates the output shaft and rotates the motor in the reverse direction to the direction indicated by the rotation direction indication signal, the speed signal is not entered to the reverse rotation.
